Suiden Spot Coolers are highly portable refrigerative air conditioning units specifically designed for industrial applications, emphasizing ease of use with no installation required, powerful cooling capabilities, and low running costs. Equipped with casters, these units offer immediate, targeted cooling, capable of lowering temperatures by 8-12°C and even reaching -12°C under specific conditions (37°C ambient, 60% humidity). They effectively cool without increasing humidity, thereby safeguarding sensitive equipment and promoting user well-being. Technically, the SS-27 series utilizes R32 refrigerant, an environmentally friendly choice with a significantly lower Global Warming Potential than older alternatives. Other models, including the SS-40 and SS-56 series, employ R407C. Cooling capacities range from 2.7kW (9,200BTU) to 5.6kW (19,000BTU), all operating on a single-phase 220V, 50Hz power supply. Key specifications include drain tank capacities from 4L to 20L, power consumption between 0.8kW and 2.8kW, and unit weights from 32kg to 90kg. These units are designed for operating conditions typically between 18°C (50% humidity) and 45°C (40% humidity), with a capacitor lifespan of approximately 25,000 hours or 10 years. The operational principle involves separating cool and hot air, efficiently directing cool air to specific work zones while exhausting hot air via a duct. The cool air ducts are highly flexible, allowing for 300-degree rotation, precise directional adjustment, and automatic swing modes (45-90 degrees). For continuous operation, a drain hose can be connected in place of the internal tank. A wide range of optional accessories, such as various ducts and filters, further enhances adaptability. These spot coolers are ideally suited for diverse industrial environments, including server rooms, casting processes, assembly lines, production lines, and warehouses, providing essential comfort and maintaining optimal conditions in demanding settings.
